Tool Version

  • v2.5

Setup

The program supports two modes:
  1. Host/Standalone Mode is used to passively monitor module statistics during host/standalone operation.

  2. LMAC Test Mode is used to control and monitor modules at LMAC level. For LMAC test mode, see Common RAM Mode Tool Setup Instructions.

Operation Types

The program supports four types of operation:
  1. TX (LMAC Test Mode Only):

    Passive monitoring with transmission parameter configuration.

  2. RX (LMAC Test Mode Only)

    Passive monitoring with reception parameter configuration.

  3. MONITOR

    Passive monitoring without configuration.

  4. NOISE (LMAC Test Mode Only)

In addition, the program features a REPLAY functionality, which can be accessed via the menu bar.

Configurable Parameters

  • COUNTRY (TX/RX/NOISE):

    is used to select the operating country code.

  • Channel & BW & MCS (TX/RX):

    is used to set the operating frequency, bandwidth and MCS index. The MCS parameter does nothing for RX mode and is purely for logging purpose only.

  • TX Power (TX):

    is used to set the TX power level.

  • Packet Length/Interval:

    is used to configure the packet length and the inter-packet interval.

  • A-MPDU:

    is used to toggle A-MPDU usage option.

  • Rate Control:

    is used to toggle Rate Control usage option. If toggled on, the MCS index will dynamically change during operation.

  • Short GI:

    is used to toggle Short Guard Interval (SGI) usage. If turned off, the guard interval type defaults to Long Guard Interval (LGI).

  • Ack Type (TX):

    is used to set the ACK type. Available options are NONE, NDP and NORMAL.
